What’s happening after a long outage (say 48 hours)? Let’s say that I failover to my recovery site and during 48 hours, there’s no communication between the two sites. Then my production site comes back up and I want to “move” back to it.
Does Zerto keeps track of modified blocks on the recovery site for 48 hours and only sync those blocks or does it perform a full delta sync of all VPG (aka reading everything on both sides to compare)?
In other words : I have 200 TB of protected storage, I failover and for 48h there are 2 TB of blocks modified on the recovery site, when the communication is restored, does Zerto sync 2 TB or 200 TB?
When the system or service comes back online after the outage, a full delta sync may be necessary to ensure that all changes made during the outage period are properly synchronized with other systems or services. bitlife
